Prepare Heartland Lasagna noodles according to package directions. Rinse with cold water and drain well. Cut noodles into squares and toss in one tablespoon of vegetable oil to prevent sticking. Set aside.

In a small serving bowl, mix Parmesan cheese and cottage cheese and season with salt and pepper. In a separate small bowl, mix cooked ground beef with pepperoni slices. Place about one cup of warmed spaghetti sauce in small serving bowl. Place mozzarella cheese, olives and mushrooms in separate serving bowls.

Set up all serving bowls with ingredients and lasagna noodles in buffet style.

Let individuals build their own lasagna stacks by layering ingredients with noodles, customized to their taste. Stacks can be served at room temperature or microwaved for about 45 seconds, if desired to be served warm. Store leftover lasagna noodles in an airtight container in the refrigerator to prevent drying and hardening.
